Cuộn dây cho 0,12mm² hoặc 0,25mm²

Wire spool for 0,12mm² and 0,25mm² 

I have designed a wire spool on which 100m of 0.12mm² or 100m of 0.25mm² cable can be unwound. When you have printed the spool you can use a sewing machine to wind the cable. To do this, simply wrap a lower thread roll once with adhesive tape so that it fits better. Then put it on and wind it up. Do not wind too tightly because then the bobbin and the wire spool rotates freely. 

Have fun printing.
